Worried someone is watching? Check into any hotel, Airbnb, or rental and sweep the room for hidden cameras and spy devices. NSpy is a hidden camera detector that turns your iPhone into a portable counter-surveillance kit — no extra gear, no tech skills required. Hidden cameras are smaller and cheaper than ever. A pinhole camera can hide inside a smoke detector, an alarm clock, a power outlet, a USB charger, or an air vent. NSpy gives you three detection methods to help you look for them and check your space. How NSpy works • Wi-Fi network scanner — lists the devices on the same Wi-Fi network and flags camera-like and microphone-like hardware as suspicious, so you know where to look first. • Infrared (IR) view — dim the lights and use the color filters to help you spot the glow of night-vision IR LEDs, which is invisible to the naked eye. • Magnetic field detector — uses your phone's magnetometer to show magnetic changes near clocks, vents, outlets, and smoke detectors, helping you narrow down where to look. What you get • Three scan methods in one app, each started with one tap • Per-device detail view to inspect anything suspicious on the network • Flags network-connected microphones and audio devices on the same Wi-Fi • Step-by-step "how it works" guide so you know exactly what to look for • Clean, private interface — your scans stay on your device • Multi-language support and responsive in-app support Who it's for • Travelers checking into hotels, motels, and short-term rentals • Airbnb and vacation-rental guests who want peace of mind on arrival • Renters and tenants inspecting a new apartment or room • Parents checking a child's bedroom or a babysitter's space • Business travelers securing a room before a private meeting • Domestic-violence survivors and anyone worried about being watched or stalked • Anyone uneasy about a bathroom, changing room, locker room, dressing room, or gym Why NSpy When you walk into an unfamiliar space, you shouldn't have to wonder who's recording you. NSpy combines a Wi-Fi scanner, an infrared camera viewer, and an EMF/magnetic detector into one focused privacy tool built for one job: helping you check for hidden cameras, spy gear, and listening devices. It's a hidden camera finder and bug detector you can carry everywhere. A few quick notes: NSpy is a privacy and counter-surveillance scanning tool, not a guarantee against every covert device. No detector app can promise it will find 100% of hidden cameras, so use NSpy together with a careful visual inspection of mirrors, vents, and electronics. NSpy is not an antivirus, a Wi-Fi speed test, or a Bluetooth tracker finder. Download NSpy and take privacy back into your own hands. Scan your next hotel, rental, or meeting room with confidence. Pro unlocks unlimited scans, infrared color filters, magnetic field detection, and complete device reports. NSpy offers optional paid subscriptions for access to certain features. Subscriptions renew automatically unless cancelled at least 24 hours before the end of the current period, and can be managed or cancelled at any time in your App Store account settings.
